You can actually do it either way, you could distribute first and then combine, you would get the same answer. I guess it just depends on what you find easier. Here is how to solve it both ways:
Combining First:
8(5x+9x+6)=160
8(14x+6)=160
112x+48=160
112x=112
x=1
NOT Combining First:
8(5x+9x+6)=160
40x+72x+48=160
112x+48=160
112x=112
x=1
so, you would get the same answer both ways, it is of personal preference what you do first.

Answer:
A histogram often looks similar to a bar graph, but they are different because of the level of measurement of the data. Bar graphs measure the frequency of categorical data. A categorical variable is one that has two or more categories, such as gender or hair color

i hope this helped :)
Answer: x^3 - 1 = (x - 1)(x^2 + x + 1)
Explanation:
This is a type of factorizing called the sum or difference of 2 cubes:
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
The sum of the cubes is factored as:
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
In this case, we have: x^3 - 1 so follow the rule above.
x^3 - 1 = (x - 1)(x^2 + x + 1)
